Question 955092: State whether each function given below is symmetric about either axis or the origin.
a. y = x + 3
b. y = x - x
c. y = √|x|
Here's my answer, but I'm not sure about it:
a. symmetric about the y axis
b. symmetric about the origin (not sure)
c. symmetric about both axes and the origin
Answer by macston(5194) (Show Source): You can put this solution on YOUR website!
x-axis symmetry:Replace y with -y is equivalent equation.
y-axis symmetry:Replace x with -x is equivalent equation.
Origin: Both x- and y-axis symmetry.
